I've been thinking quite a bit about documentation and the 'cost' it involves. And when I say documentation, I mean documentation in general about anything. One obvious case with the industry I'm involved in is user documentation (a.k.a The Manual). Creating great features in software takes time and effort but if it is not documented then the user won't even know about it and finally it never gets used. But then while documenting it you just wish that you're working on the next cool thing rather than have to write this up. So finally you end up not doing the documentation or doing it rather badly.
Same thing with this blog writing. I have been doing some pretty interesting things with my phone (rooting it and using cynogenmod and all), some pretty significant life changes (my grandmother passed away) and a lot of other things which I should probably like to remember better or reflect more on it but not documented (here or anywhere permanent) and it would probably be lost in the sands of time before long.
I guess finally it falls on how you view it. If you see it as a burden, something which has to be done, then that's how it would be. But if you see it as a way to empoyer the user, or reflect more on your life, then that's how it would be too. And time... well.. that's the price which has to be paid no matter what. It ain't going to write itself.
